677-TabulaTIME: Pan-Cancer Landscape of Profibrotic Ecotypes

The paper introduces TabulaTIME, a massive pan-cancer single-cell resource that integrates data from over four million cells across 36 different cancer types. By utilizing advanced computational frameworks, the researchers identified a specific group of CTHRC1+ cancer-associated fibroblasts that reside at the boundary between healthy and malignant tissue. These cells appear to create a physical barrier that prevents immune cells from infiltrating the tumor. The study also highlights a profibrotic ecotype formed by the interaction of these fibroblasts with SLPI+ macrophages, which contributes to poor patient outcomes. Ultimately, this comprehensive landscape provides a navigational map for understanding the tumor microenvironment and identifying new therapeutic targets to overcome immune evasion.References: Han Y, Zhang L, Sun D, et al.
